I guess some code in the background thread calls a yielding function
inside save-excursion or something? I'd try running with a breakpoint
in set_point_both and temp_set_point_both, with commands that show the
backtrace and immediately continue the program. Then you might see
the culprit.
Or maybe Michael will know where that happens given the description.

That is not necessarily a bug: if some thread performs some prolonged
calculation, no other thread will be able to run, and no input will be
accepted. Just like with a single thread.
Thanks.
